Hydrogen delaying the formation of Guinier-Preston zones in aluminium alloys
Guillaume Hachet, Xavier Sauvage
The consequences of hydrogen on the formation and growth of GP zones during natural ageing in an Al-5Cu alloy is investigated experimentally down to the atomic scale and numericall…
Influence of hydrogen vacancy interactions on natural and artificial ageing of an AlMgSi alloy
Guillaume Hachet, X Sauvage
The influence of hydrogen on the structural evolutions of an Al-Mg-Si alloy during natural and artificial ageing was investigated experimentally. The aim of the study was a better…
Understanding the role of Ca segregation on thermal stability, electrical resistivity and mechanical strength of nanostructured aluminum
Xavier Sauvage, Fabien Cuvilly, Alan Russell +1
Achieving a combination of high mechanical strength and high electrical conductivity in low-weight Al alloys requires a full understanding of the relationships between nanoscaled f…
Multifunctional properties of composition graded Al wires
Cui Yang, Nicolas Masquellier, Camille Gandiolle +1
The potentiality of composition graded AlMgSi wires for optimized combination of electrical conductivity and torsion strength has been investigated. Composition graded wires were o…
Preferential evaporation in atom probe tomography: an analytical approach
Constantinos Hatzoglou, Solène Rouland, Bertrand Radiguet +5
Atom probe tomography (APT) analysis conditions play a major role in the composition measurement accuracy. Preferential evaporation, which significantly biases apparent composition…
Achieving highly strengthened Al-Cu-Mg alloy by grain refinement and grain boundary segregation
Takahiro Masuda, Xavier Sauvage, Shoichi Hirosawa +1
An age-hardenable Al-Cu-Mg alloy (A2024) was processed by high-pressure torsion (HPT) for producing an ultrafine-grained structure. The alloy was further aged for extra strengtheni…
